2. INTRODUCTION

Indirect fired heaters are sophisticated, reliable, and highly efficient heaters. Ideal for places where there's limited ventilation, or where people are present, as they deliver huge volumes of clean, dry, fume free heat safely and economically. The Sealey 170,000Btu/hr Indirect Space Warmer® has a 50kW heat output ideal for heating marquees, events, halls, workshops, warehouses, construction sites and more. Combustion by-products are exhausted out of the top of the heater through the flue. With a thermostat control it allows you to set a required ambient temperature and maintain it. The thermostat will switch the heater on and off as required to maintain the set ambient temperature, this saves fuel and adds extra convenience. The indirect heater includes a stainless-steel combustion chamber with fan cooling, built-in flame sensor, Danfoss pump, electronic flame control and electronic control panel which ensures reliable performance. Fitted with a flame-out device which cuts the fuel supply when the flame is inadvertently extinguished or if the fuel has run out, ensuring maximum safety. Suitable for use with Kerosene or Diesel. Large wheels and a handle make the heater easy to transport, position and re-position where required on site. Ducting is available, Model No. ABI1700AK1 sold separately. Flue system with rain cover is available, Model No's ABI1700AK2, ABI1700AK3, ABI1700AK4 sold separately.
